Creasebook / Privacy
Your data,
in plain language.

Your goalie notebook
Creasebook requires an account. Your email address, account identifier, family membership, goalie profiles, game records, shot entries, source references, edit history and saved score-sheet photos are stored in Google Firebase. Invited family members can access the same notebook and its original photos according to their owner, editor or viewer role. Other families cannot access your notebook.
Existing local notebooks, pending edits and available source photos are moved into your signed-in family. The old runtime copies are removed only after cloud saving is confirmed. Cloud records and deletions take priority over stale local copies. Old data that cannot yet be moved stays on its original device until migration can finish.
Optional score-sheet reading
When you choose Read with AI, Creasebook sends a resized copy of your selected score-sheet photo through its private Firebase server to OpenAI for transcription. Original photo metadata is removed first. The server creates overlapping close-ups and a high-contrast ink view of the same image to read small handwriting and shot dots; these are used for transcription and are not saved as separate source photos. You review and correct the results before saving a game; you can also enter the sheet manually without sending it to OpenAI.
The scan service does not log photos or unreviewed AI responses. When you save the reviewed game, its source photo is saved separately in private family cloud storage. Daily scan counters tied to your account and family help limit service usage.
The request disables OpenAI response storage. OpenAI may retain content for abuse monitoring under its own service policies; this is not a promise of zero retention. See OpenAI’s API data controls.
Accounts and device storage
Firebase Authentication handles sign-in, email verification and password recovery. Creasebook does not store your password in its game database. Authentication credentials and small display preferences stay on your device. Game records, pending edits and downloaded photos are held in memory while the app is open; new notebooks and photos are not persisted to device storage. An internet connection is required to load and save your notebook. Keep Creasebook open while saving is in progress.
Keeping and deleting data
Swipe a game in History and confirm Delete game to remove it from your family’s visible history on all devices. The edit history retains the deletion and prior edits for sync and conflict handling. Sign out to clear the current notebook from the screen. Leaving a family removes your membership but keeps that family’s records for its remaining members. Removing a member blocks future server access; it cannot recall copies already made.
To delete your account, open My data → Delete account. First remove other members from families you own. Deletion removes your memberships, owned family notebooks, their source photos and edit history, and your Firebase account. Contributions in families owned by someone else remain with that family. Original photos in your camera roll and previously exported files remain under your control.
Analytics and advertising
Creasebook does not enable advertising, tracking or Firebase Analytics. Firebase processes operational information needed to authenticate accounts and provide the service. See Firebase’s privacy information.
